RAIL-TIE.

Application filed April 16, 1915.

To all whom it may concern:

Be it known that I, MARIA A. GILLILAND, a citizen ofthe United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in RailTies, of which the following is a specification.

The present invention relates to improvements in rail ties and means for securing the rails to the ties.

In carrying out my invention, it is my purpose to construct a tie from a single str p of suitable metal, which shall be simple in construction, strong and durable in operation, and which shall possess a sufiicient amount of resiliency to effectively cushion the rails, thus preventing breakagco'f the tie or of the rails under the strain incident to the weight of rolling stock imparted thereto. I also aim to construct a metal tie in such a manner that when the same is arranged within the road bed the danger of sinking is reduced to a minimum and the danger of longitudinal or lateral movement will be entirely obviated.

It is a still further object of my invention to provide a metallic railroad tie having a hollow body portion that is substantially triangular in cross section, the meeting sides of the said body, at the apex thereof, providing longitudinal abutting surfaces at right angles, forming horizontal flanges, and to further provide longitudinal movable rail receiving members or clips which co-act with the mentioned horizontal flanges in such a manner as to retain the same in proper parallelism and to prevent spreading or opening of the same, the securingelements for attaching the rail seats to the ties being also utilized to engage one of the longitudinal edges of the base flange of i the rail to retain the said rails upon the said seats.

It is a still further object of the invention to construct metallic ties which will include a hollow body portion that is substantially triangular in cross section, to provide angular sides of the said body with outwardly bulging portions forming ribs, likewise to provide the base or body with similar ribs which are arranged one between two of the side ribs, the said ribs co-engaging with the road bed, when the said road bed is tamped around the tie, to prevent the lateral or longitudinal movement of the said Specification of Letters Eatent.

tie, and to insure a firm seating of the tie in the road bed.

l/Vith the above objects in view the invention consists in the features of construction, combination and arrangement of parts hereinafter described and claimed, reference being had to the accompanying drawings.

In the drawings Figure l is a perspective view of a tie and rail seats therefor con structed in accordance with my invention, the rails resting upon and being secured to the rail seats; Fig. 2 is a transverse sectional view approximately on the line 22 of Fig. 1; Fig. 3 is a detail side elevation of the same; Fig. l is a perspective view of one of the rail seats; Fig. 5 is a view of the blank from which the tie is formed; Fig. 6 is a View of the blank from which the rail seat and clamp are formed; Fig. 7 is an end view of a tube from which the tie may be constructed to accord with my invention; Fig. 8 is an end view of the tie formed from the tube illustrated in Fig. 7; and Fig. 9 is a view of a still further modified form.

In reducing my invention to practice I employ a sheet or strip of metal of the desired size and thickness, the said metal being of suiticient strength to withstand the strain to which it is subiected, and at the same time embodying su'l'ficient resiliency to yield under the weight of the rolling stock and otler no abrupt resistance to the rails supported thereon when the weight of the said rolling stock is upon the rails. By a suitable stamping machine the plate, illustrated in Fig. 5 of the drawings. is subjected, first, to a pressure which bulges the same outwardly on one of its faces to provide the same with ribs hereinafter more fully referred to. A second impression from a suitable die bends the plate to provide a substantially triangular body 1. The body at form the same with transversely arranged ribs 8, and each of the ribs 8 is arranged intermediate of the ribs 6.

By the peculiar construction and arrangement of the tie it will be noted that when the same is arranged within the road bed and the said road bed tamped around the tie, the flat bottom 7 will prevent the sinking of the tie in the said road bed and the transverse ribs will prevent the longitudinal movementof the tie, while, when the said road bed is tamped around the inclined sides, the peculiar formation of the said sides in connection with the ribs 6 will assist in preventing the said longitudinal movement and also prevent a lateral movement of the tie.

From practice it has been found'that no means forconnecting the abutting members 2 is necessary, but in order to retain the said members in abutting'or contacting relation as well as to retain the'flanges 3 in proper horizontal position or alinement, and further to provide means for securing the rails 9 upon the tie, I employ rail seats indicated by the numeral 10. Theseseats, as illustrated in Fig. -1 of the "drawing,'are also formed from a single piece or strip of suitable metal and are stamped to provide a horizontally straight body 11, which has one of its ends formed with an inturned angular flange 12, the said flange overlying the body and corresponding or agreeing with the inclined upper surfaces of the base flanges 13 of the rails9, and the flange 12 is adapted to frictionally contact with the said base flange uponone'of the'sidesof each of'the rails 9. The longitudinal edges of the body 11 of each of the combined seat and clamps 10 form right angular depending flanges 14,

the ends of which extend inwardly, also at a right-angle, as indicated'by the numeral 15.

The flanges are-arranged away'from but are in a'parallel line with the un'der'face of the flatbodyll. Theright angular flangesl-fl, and the horizontal flanges 15, are so arrangedthat the same, when inserted longi- 'tudinally"from 'the opposite ends of the "horizontal'flangesfi of the tie proper, will frictionally contact with both the outer longitudinaledges of the said flanges or head portions '3as well aswith the other 'faces'of' thesame. It'will be'note'd that the members'lO effectively-retain the flanges 3 against spreading. The vertical portions 2 are primarily provided to permit of the arrangement of the nuts 15 between the "flanges'B and the inclined sides' l'of the hollow' body of the tie,"'whilejbolts 16 have their shanks passed'through suitable openings in the'body, 11 of the members 10 as well as through openings in the flanges 3 and areengaged by the said nuts 15. The

heads ofthe 7 bolts 16 contact with the base flanges-"of" the rails opposite" the portions of the said base flanges engaged by the flanges 12 of the members 10.

In Fig. 7 Ishow a tube which may be placed upon a suitable rolling machine to produce a tie similar to that illustrated in Fig. 8 of the drawings.

In Fig. 9 I have illustrated a still further modified form of my improvement; The structure disclosed in this figure is formed from a single sheet or strip of suitable metal and includes a triangular body A'which has its sides formed with vertical extensions B, the said extensions having their ends flanged outwardly inopposite directions, as indicated by the characters C. The horizontally straightportions C are bent upon themselves as indicated by the characters D, and the portions C and I) provide the upper face or head of the tie. The'ends oft-he portions D are bent downwardly, as at E between the vertical members B, and contact with each other as well as with the innerfaces of the said members B. The portions E are provided with angular'extensions F, the same diverging in opposite directions from their contacting portions and the ends of the said-members F rest upon the base of the substantially triangular body AJ By spreading the legs or angular members F it will be noted that the resiliency of the head D is not materially affected, and the slidable rail receiving members or seats, heretofore referred to, engage with the longitudinal edges of the face or head of the tie as well as rest di rectly upon the upper surface of the said head, and securing nuts and bolts, similar to those previously described, are employed tion with Figs. 1 to'z5.

'Having thus described the invention, what:

I claim is: p

-1. A tie formed-of a singlesheet of metal, stamped .to provide a substantially triangular body, the meeting edges of whichbeing'extended to provide abutting surfaces,

and the said surfaces having their ends flan'ged'outwardly in opposite directions to form the top of the tie, a rail seat having its longitudinal edges flanged to provide ways,

,said seat'having one of its ends provided with an angular flange forming a rail engaging lip, the seat'adapted to be arranged upon the top for longitudinal 'movement and have its longitudinal flanges engage with the longitudinal edges of the underfaces of the face of the tie, means for securing the seat upon the face of the tie, and said'meansadaptedto co-act with therail,

* as and for the purpose set forth.

*2. A- metal tie" formed from- 2; single sheet and including a substantially triangular body, the ends of which being extended in parallel relation and being flanged in opposite directions parallel with the base of the body, said flanges being bent upon themselves and lapped to provide a head for the tie of a thickness twice as great as that of the seat, the said lapped portions having their ends extended toward the base between the extending portions of the meeting ends of the base and contacting with each other and with the said extending portions of the base, the said contacting portions being further extended divergently and contacting with the base.

3. A metal tie formed from a single sheet and bent to form a triangular body, the base portion of the body as well as the angular sides thereof being depressed to provide outwardly projecting ribs and the ribs of the base being disposed intermediate of the ribs of the sides, said sides having their meet ing ends extended vertically to provide abutting surfaces and the edges of the said surfaces being bent in opposite directions to provide the tie with auxiliary straight flanges, a rail seat having its opposite edges bent and formed with inturned portions positioned upon the flanges, whereby the edges and the underfaces of said flanges will engage the inturned portions of the rail flanges to prevent the bending of said rail flanges, each of said rail seats having one of its edges formed with a transverse lip which is adapted to engage with one of the edges of the flange of a rail, securing elements passing through each of the seats and through the flanges of the tie, said securing elements contacting with the longitudinal edge of the rail flange opposite that engaged by the lip, and means for securing the said elements upon the flanges of the tie.

In testimony whereof I aflix my signature in presence of two witnesses.
